title: Sauchinone blocks methamphetamine-induced hyperlocomotion and place preference in mice.
abstract: Sauchinone is a phytochemical known as a nitric oxide (NO) inhibitor. NO is a kind of neurotransmitter and involved in psychotic effect of abuse drug. In present, we carried out a study on the effect of sauchinone on methamphetamine-induced alteration of behavior in mice. Locomotory activity and conditioned place preference (CPP) were used to evaluate behavioral changes. As a result, sauchinone inhibited the methamphetamine-induced hyperlocomotion in dose-dependent manner, whereas sauchinone had no effect on normal locomotory activity. The inhibitory effect of sauchinone on methamphetamine-induced hyperlocomotion was reversed by treatment of molsidomine, a NO donor. Sauchinone also significantly blocked the acquisition and expression of CPP induced by methamphetamine in mouse. However, it did not produce place preference or place aversion, when it was treated alone in animals. Taken together, sauchinone blocked drug reward-related behavior as well as acute hyperlocomotion induced by methamphetamine treatment.
